4. Remove the access panel on the left side of the
engine compartment. The drain valve is located
in an access port of the fan shroud. Open the
drain valve. Allow the coolant to drain into a
suitable container.
5. Close the drain valve. Fill the system with a
solution which consists of clean water and of
cooling system cleaner. The concentration of the
cooling system cleaner in the solution should be
between 6 percent and 10 percent.
6. Start the engine. Run the engine for 90 minutes.
Stop the engine. Drain the cleaning solution into
a suitable container.
7. While the engine is stopped, flush the system
with water. Flush the system until the draining
water is transparent.
8. Close the drain valve.
9. Add the coolant solution. See the following
topics:
•
Operation and Maintenance Manual, “Cooling
System Specifications”
•
Operation and Maintenance Manual, “Refill
Capacities”
Note: If you are using Caterpillar antifreeze, do not
add the supplemental coolant additive at this time
and/or change the element at this time.
10. Start the engine. Run the engine without the
radiator cap until the thermostat opens and the
coolant level stabilizes.
11. Maintain the coolant level within 13 mm
(0.5 inch) of the bottom of the filler pipe.
12. Install the radiator cap. Replace the radiator cap
if the gasket is damaged.
13. Stop the engine.
14. Replace the access panel. Close the access
door.

Cooling System Coolant (ELC)
- Change
SMCS Code: 1353; 1395
Pressurized system: Hot coolant can cause seri-
ous burn. To open cap, stop engine, wait until ra-
diator is cool. Then loosen cap slowly to relieve
the pressure.
NOTICE
Mixing ELC with other products will reduce the effec-
tiveness of the coolant.
This could result in damage to cooling system compo-
nents.
If Caterpillar products are not available and com-
mercial products must be used, make sure they
have passed the Caterpillar EC-1 specification for
pre-mixed or concentrate coolants and Caterpillar
Extender.
For information about the addition of Extender
to your cooling system, see the Operation and
Maintenance Manual, “Cooling System Extended
Life Coolant Extender - Add” or consult your
Caterpillar dealer.
